Audio Visualizer module 1

The Audio Visualizer module, version 1 — TRCC's first installable module.

It draws what your computer is playing as a panel's background, with the
theme's mask and readings on top: TRCC Pipes, MilkDrop, the Cavalier family,
KarmaViz and the rest of the gallery.

You do not download this by hand. From TRCC 9.12.0 on, open Modules →
Get modules and install it there; the CLI is trcc system modules install visualizer. TRCC checks this bundle's signatures — the author's and the
maintainer's countersignature in the signed module index — before it unpacks a
byte. The zip here is what that install fetches.

• needs TRCC 9.12.0 or newer (older versions have no module system)
• asks for: events, panels, background, settings, themes, sound, gpu, files
• built from the tagged source in this repository, packed byte-for-byte
  reproducibly by dev/tools/module_bundle.py

Why it is a module: the Visualizer is an add-on rather than part of what TRCC
is, so no wheel, distro package or installer carries it any more. If your panel
was playing a visual before you upgraded, TRCC keeps that choice and tells you
to install this — and the panel goes straight back to it.
